Jennifer Lopez looked like she was channelling a Disney princess in her frothy cappuccino-coloured prom dress at the Muhammad Ali's Celebrity Fight Night XIX bash held at JW Marriott Desert Ridge Resort & Spa in Arizona this weekend.
The only nod to naughty? The black lace halter neck added to the sweetheart neckline.
J-Lo posed for pics on the red carpet with her beau, Casper Smart, and paired the look with matching nude and black-striped court heels and tousled long blonde locks.
